This is a huge if...
If we end up trading for another late draft pick, and we won the draft lottery. Would you trade the 1st overall pick (Anthony Davis) and the late pick to the Hornets for their 2 picks if they landed in the 2nd or 3rd spot? They most likely will have Minnesota's pick as well, which will be in the lottery.
Doing this we would be able to select Barnes or MKG and then draft from 10-15th again. We would have a chance to take any point guard or the best player available.
We are already deep at the PF position, and I think it's worth keeping Bargs, and one of Ed or Amir
